      Do you love holidays but hate the increase weight that follow? You are not alone.

      Holidays are happy days with pleasure and delicious foods. Many people, however, are worried about the

weight that comes along with these delicious foods. 

      With proper planning, though, it is possible to control your weight. The idea is to enjoy the holidays but

not to eat too much. You don't have to turn away from the foods that you enjoy. The following suggestions

may be of some help to you.

      Don't miss meals. Before you leave home for a feast (宴会), have a small, low-fat snack. This may help

to keep you from getting too excited before delicious foods. 

      Begin with clear soup and fruit or vegetables.

      A large glass of water before you eat may help you feel full.

      Use a small plate; a large plate will encourage you to have more than enough.

      Better not have high-fat foods. Dishes that look oily or creamy have much fat in them.

      Choose lean meat. Fill your plate with salad and green vegetables.

      If you have a sweet tooth, try mints (薄荷) and fruits. They don't have fat content as cream and chocolate.

      Don't let exercise take a break during the holidays. A 20 minute walk after a meal can help burn off excess

calories.
